Not Two.
Not Three (Trio).
Not :
oh it's a mashup of abc to xyz,
oh I can't narrow it down,
oh it's everything played by this musician,
oh no one influenced me, I am an original

It can be :
a rhythmical groove, a small part on a song, a backing track, a few chords, a solo, a whole track.
Any genre.
Any keyboard instrument.
Giving reasons as to why.

For me :
After years of listening to Satie, Debussy, Chopin, Scott Joplin, Oscar Peterson, McCoy Tyner, Bill Evans, Nina Simone, Fela Kuti, Billy Preston, Joni Mitchell, Brenda Russell, Herbie Hancock, George Duke, Keith Jarret, Chic Corea, Abdullah Ibrahim, Bernie Worrell, Ray Manzarek, Gregg Rolie, John Lord, Joe Zawinul, Wendy Carlos, Vangelis, Tony Banks, Keith Emerson, Rick Wakeman, Greg Philingaines, Bill Sharpe, Bheki Mseleku.
It is a Rhodes solo in a guitar hit song released May 1986.
The solo evoking melancholy, evoking love and lost love, evoking summer and end of summer.
I think you might have guessed.
Played by Max Middleton.
On The Beach by Chris Rea.

The whole of Max's playing.
2min32 -2min45
Particularly solo
4min47 - 6min47.
I've realised this just today, listening to various key tracks I've done.
I wasn't doing it consciously, it just happened.
I saw Max with Chris 2017 November 26 Hammersmith Apollo.
I wish I had the chance to kiss Max's hands express my gratitude.
